SOUTH KOREAN GOLD MARKING
Three marks that may appear on modern South Korean made gold objects:
The above is the mark of the Korea Jewellers' Association. The association was established in 1966 and marking of manufacturing members products started at the same time, but the scheme was unsuccessful and fell by the wayside at an unknown date and the activities of the association suspended. However, the Korea Jewellers' Association was resurrected in 1987 in readiness for the 1988 Olympics that were held at Seoul, and marking reintroduced.
Around the same time, 1987, two other organisations were formed:
The Korea Jewelery Manufacturers' Association, who marked their member's products with the below symbol:
and The Precious Metal & Gem Trade Laboratory, who marked products with the below symbol:
All three organisations and markings appear to be unofficial, but are apparently subject to government inspection. Three gold standards are recognised, 24, 18, and 14 carats.
The above information that I have gleaned, could use confirmation/additions/corrections, and of course, actual examples.
